A nurse in a prenatal clinic is teaching a group of clients about nutrition requirements during lactation. Which of the following statements should the nurse make?

Choice a reason:
Panting can help control the urge to push and is often recommended during the crowning stage to prevent tearing and to allow the perineum to stretch gradually. It can also help manage the pain and provide the baby with a gentle descent.

Choice b reason:
Slow-paced breathing is generally advised during the earlier stages of labor to help manage contractions and maintain relaxation. However, during the crowning stage, slow-paced breathing might not be effective in controlling the strong urge to push.

Choice c reason:
Telling the client to go ahead and push without proper guidance could lead to rapid delivery, which increases the risk of perineal tearing. The nurse should instruct the client on when and how to push effectively, often during a contraction, with controlled effort.

Choice d reason:
Taking a deep, cleansing breath can be calming and help the client focus, but it does not directly address the immediate need to control the pushing during crowning. Controlled breathing techniques specific to the delivery stage are more appropriate.

Choice A reason:
Initiating pushing in a client with suspected placenta previa is contraindicated. Placenta previa is a condition where the placenta covers the cervix, and pushing could lead to severe bleeding and compromise both the mother and the fetus. The normal labor process involves pushing only after full cervical dilation, and in the case of placenta previa, this could exacerbate the condition.

Choice B reason:
Preparation for cesarean birth is the correct action when placenta previa is suspected. With placenta previa, vaginal delivery could cause significant hemorrhage due to the placenta's position over the cervical opening. A cesarean birth bypasses the cervix, thereby avoiding disruption of the placenta and preventing excessive bleeding.

Choice C reason:
Magnesium sulfate is used in obstetrics to prevent seizures in preeclampsia and to delay preterm labor, not for placenta previa. While it is important to manage the client's overall condition, magnesium sulfate would not address the immediate concern of potential hemorrhage due to placenta previa.

Choice D reason:
An examination to determine cervical status in the presence of placenta previa should be avoided unless absolutely necessary and performed under controlled conditions, such as in an operating room where a cesarean delivery can be performed if needed. Digital cervical examinations can dislodge the placenta and cause bleeding.
